Bases: pymeasure.instruments.instrument.Instrument

This is the class for the DSP 7265 lockin amplifier

property adc1

Reads the input value of ADC1 in Volts

property adc2

Reads the input value of ADC2 in Volts

property dac1

A floating point property that represents the output value on DAC1 in Volts. This property can be set.

property dac2

A floating point property that represents the output value on DAC2 in Volts. This property can be set.

property dac3

A floating point property that represents the output value on DAC3 in Volts. This property can be set.

property dac4

A floating point property that represents the output value on DAC4 in Volts. This property can be set.

property frequency

A floating point property that represents the lock-in frequency in Hz. This property can be set.

property harmonic

An integer property that represents the reference harmonic mode control, taking values from 1 to 65535. This property can be set.

property id

Reads the instrument identification

property mag

Reads the magnitude in Volts

property phase

A floating point property that represents the reference harmonic phase in degrees. This property can be set.

property reference

Controls the oscillator reference. Can be “internal”, “external rear” or “external front”

property sensitivity

A floating point property that controls the sensitivity range in Volts, which can take discrete values from 2 nV to 1 V. This property can be set.

setDifferentialMode(lineFiltering=True)

Sets lockin to differential mode, measuring A-B

shutdown()

Brings the instrument to a safe and stable state

property slope

A integer property that controls the filter slope in dB/octave, which can take the values 6, 12, 18, or 24 dB/octave. This property can be set.

property time_constant

A floating point property that controls the time constant in seconds, which takes values from 10 microseconds to 50,000 seconds. This property can be set.

values(command)

Rewrite the method because of extra character in return string.

property voltage

A floating point property that represents the voltage in Volts. This property can be set.

property x

Reads the X value in Volts

property xy

Reads both the X and Y values in Volts

property y

Reads the Y value in Volts
